Answer:
6
Step-by-step explanation:
You gotta first add up all the numbers together, and then figure out how many numbers there are. There, in this problem, we have 4 numbers. Then figure out what is the closest number that can divide by 7.
The missing volume of gas is 6.
The mean, or average, is calculated by adding up the scores and dividing the total by the number of scores.
To calculate mean add the number of quantities and divide it by number of quatities 4,5,13,?
If the mean of the data set is 7 L, find the missing volume of gas.
Let the missing value be x mean = Sum of quantities / number of quantities
⇒ [tex]7=\frac{4+5+13+x}{4}[/tex]
⇒ 7× 4=4+5+13+x
⇒ 28=22+x
⇒ x=6
